Biosemiotics

In trying to figure out exactly what "Semiotics" meant, and how it related to the class discussions we've been having, I accidentally stumbled on something very interesting to me: a whole field called biosemiotics. Biosemiotics is the study of the "production, action, and interpretation of signs in the biological realm." Below I have a picture of what I believe to be a good representation of biosemiotics: the ouroboros. The ouroboros is a common cultural, mystical, and alchemical symbol. It is representative of the continuity and infinite nature of life. Interestingly, it was also Kekule's inspiration in realizing the true structure of the aromatic ring, who claimed to have seen the ouroboros in a hypnogogic state.
